Introduction
PVQ piston pumps are in-line, variabledisplacement units and are available innine sizes. Displacement is varied bymeans of pressure and/or flowcompensator controls. An impressiveassortment of control options offersmaximum operating flexibility.
PVQs operate at quietness levels thatmeet today’s demanding industrialconditions. The sound level of each unitapproaches or is below that of theelectric motor driving it. Sound isreduced by a patented timingarrangement that also produces lowpressure “pulses” in the outlet flow. This
leads to reduced tendencies for noise insystems using PVQs.
The PVQ series is capable of operatingwith many types of hydraulic fluid.Water-content and phosphate esterfluids can be accommodated, in additionto the typical petroleum based andsynthetic fluids.
Many PVQ pumps are available in athru-drive configuration to accommodatea multitude of application and installationrequirements. Thru-drive models can becoupled to various types and sizes offixed and variable displacement pumps,resulting in a compact and versatile
package. Such a package offers lowerinstalled cost by reducing the installationsize and by requiring only one mountingpad on the prime mover.
Quiet PVQs have excellent operatingcharacteristics, and the pumps’ manycontrol and mounting options allowchoosing the optimum model for anyapplication. Additionally, PVQs possessthe same durability and long lifecharacteristics expected of the bestindustrial products in today’smarketplace. For over 75 years, theVickers name has been synonymouswith long trouble-free service.

Controls
Pressure Compensators “C” & “CM”The pressure compensator controlautomatically adjusts pump delivery tomaintain volume requirements of thesystem at a preselected operatingpressure. Maximum pump delivery ismaintained to approximately 3,4 bar (50psi) below the pressure setting beforebeing reduced. The pressurecompensator control operates on oneside of center and has an adjustmentrange as designated in the model coding.
“C” & “CM”
Pressure Compensator withAdjustable MaximumDisplacement Stop “D”The adjustable maximum stop pressurecontrol enables the maximum pumpdelivery to be externally adjusted from25% to 100% while maintaining all of thestandard features of a pressurecompensated pump. To assist initialpriming, manual adjustment controlsetting must be at least 40% ofmaximum flow position.
Remote Control PressureCompensator “CG”Exactly the same as the “C” (pressurecompensation option) except themachine operator is able to change thecompensator setting through the use ofa remote pilot relief valve, such asVickers C-175.
Electric Dual Range PressureCompensator “CD”The dual range pressure compensatorcontrol automatically adjusts pumpdelivery to maintain volume
“CG”
requirements of the system at either oftwo preselected operating pressures.
Maximum pump delivery is maintainedto approximately 3,4 bar (50 psi) beloweither pressure control setting beforebeing reduced.
Control type and pressure range aredesignated in the model code.
“CD”
Note: Graphic symbols shown withexternal valve(s) and cylinder toillustrate typical usage.
Load Sensing & PressureLimiting CompensatorsThis compensator provides load sensingcontrol under all pressure conditions upto the desired maximum. It automatically
adjusts pump flow in response to aremote pressure signal and maintainsoutlet pressure at a level slightly aboveload pressure. The integral pressurelimiter overrides the load sensingcontrol, reducing pump displacement asthe preset maximum operating pressureis reached.
Standard load-sense differential pressuresettings, by control type, follow. Seemodel code for setting range.
“C**V11B” Standard load-sensing andpressure limiting control with 11 bardifferential pressure (standard factorysetting). Includes bleed-down orifice toexhaust load-sense signal forlow-pressure standby condition.
“C**V11P” Same as C**V11B above,but with bleed-down orifice plugged.
“C**VC24B” Same as C**V11B, butwith factory differential pressure settingof 24 bar.
“C**VC24P” Same as C**V11P, butwith factory differential pressure settingof 24 bar.

With the unloading valve control thevariable pump will unload at a presetpressure. The pump will maintain this noflow, low pressure (approximately 14 bar[200 psi]) standby condition, untilsystem pressure drops to about 85% ofthe preset unloading pressure. Thepump will then return on stroke andprovide full flow until the presetunloading pressure is reached again.
With this control, an efficientaccumulator charging circuit is obtained.The pump will provide full flow to fill theaccumulator until the maximumcharging pressure is reached. Thepump then goes to a standby conditionuntil the accumulator pressure drops to85% of the desired maximum. Theaccumulator is then recharged as thecycle starts over again.
A separate right angle check valve mustbe provided to maintain the accumulatorhydraulic charge and prevent back flowwhen the pump is unloaded. The checkvalve’s internal leakage must notexceed five drops per minute. Thecontrol port must be connected tosystem pressure, downstream of thecheck valve.

Pressure CompensatorControl “C”The pressure compensator controlautomatically adjusts pump delivery tomaintain volume requirements of thesystem at a preselected operatingpressure.
Maximum pump delivery is maintainedto approximately 5 bar (70 psi) belowthe control pressure before beingreduced.

Pressure Compensator Controlwith Adjustable MaximumDisplacement Stop “D”The adjustable maximum displacementstop allows the maximum pump deliveryto be externally adjusted from 50% to100%, while maintaining the standardfeatures of the pressure compensatedpump.
Remote Control PressureCompensator “CG”This compensator is the same as the“C” compensator, except the machineoperator is able to change thecompensator setting through the use ofa remote pilot relief valve. The pumpmust not be operated with the remotecompensator port plugged; port must beconnected to a remote pilot relief valve,such as Vickers C-175. The effectivecompensator setting is the sum of thecompensator control setting and theremote relief valve setting.

Load Sensing CompensatorControl “CV6”
This control provides load sensingcontrol under all pressure conditions upto the system relief valve setting. Itautomatically adjusts pump flow inresponse to a remote pressure signaland maintains outlet pressure atapproximately 6 bar (90 psi) above loadpressure. By venting the load-sense linewith external valving (e.g., VickersDG4V-3 directional valve), when no flowor pressure demands are placed on thesystem, the pump will go to a no-flow,low pressure, energy conservingstandby mode.
This control does not include maximumpressure limitation, so a separatesystem relief valve (e.g., Vickers CS-03)is required. The system relief valve willlimit the maximum system pressure tothe selected level.

With the unloading valve control thevariable pump will unload at a presetpressure. The pump will maintain this noflow, low pressure (approximately 14 bar[200 psi]) standby condition, untilsystem pressure drops to about 85% ofthe preset unloading pressure. Thepump will then return on stroke andprovide full flow until the presetunloading pressure is reached again.
With this control, an efficientaccumulator charging circuit is obtained.The pump will provide full flow to fill theaccumulator until the maximumcharging pressure is reached. Thepump then goes to a standby conditionuntil the accumulator pressure drops to85% of the desired maximum. Theaccumulator is then recharged as thecycle starts over again.
A separate right angle check valve mustbe provided to maintain the accumulatorhydraulic charge and prevent back flowwhen the pump is unloaded. The checkvalve’s internal leakage must notexceed five drops per minute. Thecontrol port must be connected tosystem pressure, downstream of thecheck valve.
Adjustment rangePVQ20 100–210 bar (1500–3000 psi)PVQ32 100–140 bar (1500–2000 psi)
Cut-in pressure is 85% of unloadingpressure, minimum.
Setting Pressures1. Back out accumulator unloading
pressure adjustment screw to belowdesired unloading pressure.
2. Adjust desired standby pressure.
3. Set accumulator pressure byscrewing in the accumulatorunloading adjustment screw.Accumulator recharge (cut-in)pressure is a function of themaximum accumulator pressureand is not adjustable.
4. Check pressure settings andre-adjust if necessary.

Pressure Compensator Controls“C” & “CM”The pressure compensator controlautomatically adjusts pump delivery tomaintain volume requirements of thesystem at a preselected operatingpressure. Maximum pump delivery ismaintained to approximately 75 psi(PVQ25) below the pressure settingbefore being reduced. The pressurecompensator control operates on one sideof center and has an adjustment range asdesignated in the model coding.
“C” & “CM”
Pressure Compensator Controlwith Adjustable MaximumDisplacement Stop “D”The adjustable maximum stop pressurecontrol enables the maximum pumpdelivery to be externally adjusted from25% to 100% while maintaining all of thestandard features of a pressurecompensated pump. To assist initialpriming, manual adjustment controlsetting must be at least 40% ofmaximum flow position.
Remote Control PressureCompensator “CG”Exactly the same as the “C” (pressurecompensation option), except themachine operator is able to change thecompensator setting through the use ofa remote pilot relief valve, such asVickers C-175.
Electric Dual Range PressureCompensator Control “CD”The dual range pressure compensatorcontrol automatically adjusts pumpdelivery to maintain volume

Electric Dual RangePressure Compensator withMaximum DisplacementStop “CD**D”
Maximum Flow AdjustmentWith the system pressure below bothcompensator settings, loosen maximumstop adjusting screw locknut and adjustscrew to desired flow position (turningscrew clockwise decreases flow andturning screw counterclockwiseincreases flow). To lock screw inposition, tighten locknut. To assist initialpriming, adjust control setting to at least40% of maximum flow position.
Compensator Control1. With the directional valve
de-energized, loosen locknut “5” andturn the adjusting screw “4” to thedesired first stage pressure setting,then tighten locknut “5”.
2. With directional valve de-energized,turn adjusting spool “1”counterclockwise until nut “3” isbottomed in adjusting screw slot.(Second stage setting is now equalto first stage pressure setting.) Turnadjusting spool clockwise to desiredsecond stage pressurerequirements. One complete turn ofadjusting spool equalsapproximately 41 bar (600 psi).Energize solenoid and checkpressure setting. De-energizesolenoid and re-adjust if necessary.Secure this setting by tighteninglocknut “2”.
1. Adjusting spool — setssecond stage pressure
2. Locknut — 17,3 (0.68)across flats
3. Locknut — must becontained within slot ofadjusting screw as shown
4. Adjusting screw 25,4(1.00) across flats — setsfirst stage pressure

With the unloading valve control thevariable pump will unload at a presetpressure. The pump will maintain this noflow, low pressure (approximately 14 bar[200 psi]) standby condition, untilsystem pressure drops to about 85% ofthe preset unloading pressure. Thepump will then return on stroke andprovide full flow until the presetunloading pressure is reached again.
With this control, an efficientaccumulator charging circuit is obtained.The pump will provide full flow to fill theaccumulator until the maximumcharging pressure is reached. Thepump then goes to a standby conditionuntil the accumulator pressure drops to85% of the desired maximum. Theaccumulator is then recharged as thecycle starts over again.
A separate right angle check valve mustbe provided to maintain the accumulatorhydraulic charge and prevent back flowwhen the pump is unloaded. The checkvalve’s internal leakage must notexceed five drops per minute. Thecontrol port must be connected tosystem pressure, downstream of thecheck valve.
Adjustment rangePVQ25 100–210 bar (1500–3000 psi)
Cut-in pressure is 85% of unloadingpressure, minimum.
Setting Pressures1. Back out accumulator unloading
pressure adjustment screw to belowdesired unloading pressure.
2. Adjust desired standby pressure.
3. Set accumulator pressure byscrewing in the accumulatorunloading adjustment screw.Accumulator recharge (cut-in)pressure is a function of themaximum accumulator pressureand is not adjustable.
4. Check pressure settings andre-adjust if necessary.

Pressure Compensator Controls“C” & “CM”This control automatically varies pumpdisplacement to meet the system flowdemand for a constant system pressure.Displacement starts to reduce to zerowithin 14 bar (200 psi) of thecompensator setting. Power draw-off isminimized, therefore, system reliefvalves should not be required.
“C” & “CM”
Pressure Compensator Controlwith Adjustable MaximumDisplacement Stop “D”The adjustable maximum stop pressurecontrol enables the maximum pumpdelivery to be externally adjusted from25% to 100% while maintaining all of thestandard features of a pressurecompensated pump. To assist initialpriming, manual adjustment controlsetting must be at least 40% ofmaximum flow position.
Remote Control PressureCompensator “CG”Exactly the same as the “C” (pressurecompensation option) except themachine operator is able to change thecompensator setting through the use ofa remote pilot relief valve.
Electric Dual Range PressureCompensator Control “CD”The dual range pressure compensatorcontrol automatically adjusts pumpdelivery to maintain volumerequirements of the system at either oftwo preselected operating pressures.
“CG”
Maximum pump delivery is maintainedto approximately 3,4 bar (50 psi) beloweither pressure control setting beforebeing reduced.
Control type and pressure range aredesignated in the model code.
“CD”
Note: Graphic symbols shown withexternal valve(s) and cylinder toillustrate typical usage.
Load Sensing & Pressure LimiterCompensator ControlThis compensator provides load sensingcontrol under all pressure conditions upto the desired maximum. It automaticallyadjusts pump flow in response to aremote pressure signal and maintains
outlet pressure at a level slightly aboveload pressure. The integral pressurelimiter overrides the load sensingcontrol, reducing pump displacement asthe preset maximum operating pressureis reached.
Standard load-sense differential pressuresettings, by control type, follow. Seemodel code for setting range.
“C**V11B” Standard load-sensing andpressure limiting control with 11 bardifferential pressure (standard factorysetting). Includes bleed-down orifice toexhaust load-sense signal forlow-pressure standby condition.
“C**V11P” Same as C**V11B above,but with bleed-down orifice plugged.
“C**VC24B” Same as C**V11B, butwith factory differential pressure settingof 24 bar.
“C**VC24P” Same as C**V11P, butwith factory differential pressure settingof 24 bar.

With the unloading valve control thevariable pump will unload at a presetpressure. The pump will maintain this noflow, low pressure (approximately 14 bar[200 psi]) standby condition, untilsystem pressure drops to about 85% ofthe preset unloading pressure. Thepump will then return on stroke andprovide full flow until the presetunloading pressure is reached again.
With this control, an efficientaccumulator charging circuit is obtained.The pump will provide full flow to fill theaccumulator until the maximumcharging pressure is reached. Thepump then goes to a standby conditionuntil the accumulator pressure drops to85% of the desired maximum. Theaccumulator is then recharged as thecycle starts over again.
A separate right angle check valve mustbe provided to maintain the accumulatorhydraulic charge and prevent back flowwhen the pump is unloaded. The checkvalve’s internal leakage must notexceed five drops per minute. Thecontrol port must be connected tosystem pressure, downstream of thecheck valve.
Adjustment rangePVQ40 100–210 bar (1500–3000 psi)PVQ45 100–186 bar (1500–2700 psi)
Cut-in pressure is 85% of unloadingpressure, minimum.
Setting Pressures1. Back out accumulator unloading
pressure adjustment screw to belowdesired unloading pressure.
2. Adjust desired standby pressure.
3. Set accumulator pressure byscrewing in the accumulatorunloading adjustment screw.Accumulator recharge (cut-in)pressure is a function of themaximum accumulator pressureand is not adjustable.
4. Check pressure settings andre-adjust if necessary.

Pressure CompensatorControl “C”The pressure compensator controlautomatically adjusts pump delivery tomaintain volume requirements of thesystem at a preselected operatingpressure. Maximum pump delivery ismaintained to approximately 3,4 bar (50psi) below the pressure control beforebeing reduced. The pressurecompensator control operates on oneside of center and has an adjustmentrange as designated in the modelcoding.

Remote Control PressureCompensator “CG”This compensator is the same as the“C” compensator, except the machineoperator is able to change thecompensator setting through the use ofa remote pilot relief valve. The pumpmust not be operated with the remotecompensator port plugged; the portmust be connected to a remote pilotrelief valve, such as Vickers C-175. Theeffective compensator setting is the sumof the compensator control setting andthe remote relief valve setting.

Load Sensing & RemoteCompensator Control “CGV6F”This control provides load sensingcontrol under all pressure conditions upto the desired maximum pressurecontrolled by a remote relief valve. Itautomatically adjusts pump flow inresponse to a load pressure signal andmaintains outlet pressure at a levelapproximately 6 bar (87 psi) above loadpressure. By venting the load sense linewith external valving when no flow orpressure demands are placed on thesystem, the pump will go to a no-flow,low pressure, energy conservingstandby mode. A remote pressure reliefvalve is required to override the loadsensing control, reducing pumpdisplacement as the preset maximumoperating pressure is reached.
Direct Electric DisplacementControl with Remote PressureCompensator “EDG”This control varies pump flow from zeroto maximum displacement in responseto an input voltage of 0–5 volts. Thepump has an integral LVDT feedbackdevice that measures yoke position. Theelectric control is overridden by aremote pressure compensator. Whenthe system pressure reaches the remotecompensator relief valve setting, thepump is destroked to the displacementneeded to maintain the selectedpressure.

The pump’s outlet flow is used to strokethe pump. An integral sequence valvemaintains a minimum outlet pressure of10 bar (150 psi) to assure the necessarycontrol pressure is available. ControllerEDQ-L-30 is needed to drive theproportional valve and provides theappropriate interface for the LVDT.

Application Data
Fluid CleanlinessProper fluid condition is essential forlong and satisfactory life of hydrauliccomponents and systems. Hydraulicfluid must have the correct balance ofcleanliness, materials, and additives forprotection against wear of components,elevated viscosity, and inclusion of air.
Essential information on the correctmethods for treating hydraulic fluid isincluded in Vickers publication 561“Vickers Guide to SystemicContamination Control” available fromyour local Vickers distributor or by
contacting Vickers, Incorporated.Recommendations on filtration and theselection of products to control fluidcondition are included in 561.
Recommended cleanliness levels, usingpetroleum oil under common conditions,are based on the highest fluid pressurelevels in the system and are coded inthe chart below. Fluids other thanpetroleum, severe service cycles, ortemperature extremes are cause foradjustment of these cleanliness codes.See Vickers publication 561 for exactdetails.
Vickers products, as any components,will operate with apparent satisfaction influids with higher cleanliness codes thanthose described. Other manufacturerswill often recommend levels abovethose specified. Experience has shown,however, that life of any hydrauliccomponent is shortened in fluids withhigher cleanliness codes than thoselisted below. These codes have beenproven to provide a long, trouble-freeservice life for the products shown,regardless of the manufacturer.

For further information, see Vickers datasheet B-920 or I-286-S.
Fire Resistant FluidsAll pumps can be used with water glycoland polyol ester fluids. All except
PVQ16 and PVQ63 can be used withphosphate ester fluids. All pumps canbe operated to 140 bar (2000 psi) withthese fluids, except PVQ13 and PVQ32which are limited to 105 bar (1500 psi).Input speed should not exceed 1800r/min. System temperature should notexceed 54° C (130° F). Inlet vacuumshould not exceed 101,6 millibar (3 in.Hg). For more information, refer toVickers publication 579.
Installation and Start-up(Commissioning)Before a pump is started, fill the casethrough the uppermost drain port withhydraulic oil of the type to be used. Thecase drain line must be connected to thereservoir below oil level.
For multiple pump arrangements thatinclude non-PVQ sections, therequirements of the non-PVQ units mustbe considered.
Ordering ProcedureOrder pumps by the full modeldesignation. Pump displacement,mounting flange type, direction ofrotation, pump configuration, shaft endtype, seals, pressure adjustment range,and specific control functions are allspecified in the full model code.
Couplings, O-rings, capscrews andwashers must be ordered separately forall thru-drive pumps.
